Jude Law has been on a romantic date with ex, Sienna Miller - watching football in a New York bar.

The couple - who first got together after meeting on the set of the 2004 movie 'Alfie' - were spotted canoodling in Fiddlesticks in New York's West Village watching England playing in the World Cup on TV.

An onlooker said: "They had a great time watching the football it seems their relationship is back on."

The sighting comes just weeks after reports Sienna and Jude's ex-wife, Sadie Frost, are feuding over the actor.

Sadie is said to be furious the pair have rekindled their romance and allegedly told the 'Closer' actor, in an email, that Sienna would never make him happy.

A source said: "Sadie said he was mad to go back to Sienna. She said he really changes when he is with her, he becomes stressed and emotionally all over the place."

Jude reportedly showed the email rant to Sienna who was left fuming.（Bangmedia)
